Mnemora
A private memory layer that follows you across every AI app.
Mnemora is a consumer subscription that builds one persistent, user-owned memory from everything you tell any AI assistant, then serves it back to ChatGPT, Claude, and every agent app through a standard connector.

The idea in full
- What
- Mnemora is a consumer subscription that builds one persistent, user-owned memory from everything you tell any AI assistant, then serves it back to ChatGPT, Claude, and every agent app through a standard connector. Its consolidation models run on-device, distilling months of conversations into a compact profile the user can inspect and edit. Consumers pay $8-12 a month so no assistant ever starts from zero.
- Why now
- The cluster added 148 companies in 2025 and 126 already in 2026, yet the memory pieces are all developer-facing; Egoist Machines (secure, user-owned context for every AI app) and Inkbox (identity and communication layer for AI agents) in YC S26 show context ownership emerging, but nobody sells it directly to the consumer.
- Wedge: first customer and entry point
- Power users of multiple assistants who retype the same preferences daily; ship a connector for the two biggest chat apps first and let the memory file itself be the demo.
- Path to 100x
- Consumer AI subscriptions are already a $10B-plus spend line and headed toward $100B; the personal memory layer is a new category where the first product bundled as the default connector inside major agent apps becomes the identity record for the AI era. Distribution compounds: every app that pre-installs Mnemora makes the next app integrate it, and switching means abandoning your accumulated self.
- Ceiling
- If the big labs treat memory as a retention weapon and block third-party read access, Mnemora is capped as a niche privacy product under $100M revenue.
- Closest real companies, as the generator saw them
- Egoist Machines targets AI app builders with a context store; Amulet builds a file system for agents, not people. Mnemora is a consumer product where the user, not the developer, owns and pays for the memory.
- Main risk
- OpenAI or Anthropic makes portable first-party memory good enough that a neutral third-party layer never gets oxygen.
Five judges
Each judge scores every idea in the catalog with a named rubric; the venture judge decides whether a card is shown at all (4-5 is venture-grade).
Venture investor
3/5
Category-defining consumer layer, but $8-12 a month and OpenAI or Anthropic revoking read access make the upside hostage to the labs.
Bootstrapper
2/5
A $10 consumer subscription carries consumer churn and depends entirely on OpenAI and Anthropic leaving third-party read access open.
Operator
1/5
An $8-12 consumer subscription against a nuisance, retyping preferences, is a vitamin dependent on labs granting read access.
Technologist
2/5
On-device consolidation models are genuine work, but the whole product hinges on OpenAI and Anthropic permitting third-party memory reads they can revoke.
Risk
1/5
Existence depends on OpenAI and Anthropic permitting third-party memory reads, a switch the card admits either lab can flip unilaterally.
trends
2/5
Labs already ship first-party memory, so the third-party layer enters after incumbents moved, with no brief protocol or regulation securing access.

Socketry
The exchange where software vendors sell maintained, agent-ready API connections.
Socketry is a two-sided marketplace where SaaS vendors publish guaranteed-current, agent-callable versions of their APIs - tested sandboxes, auth, rate contracts, change notices - and enterprises subscribe to them for their internal agents with one bill and one security review.

Latchwork
Self-healing connectors for the long tail of small business software agents cannot reach.
Latchwork records a session against a vertical tool that has no usable API - a dental scheduler, a salon booking system, a freight dispatch app - and turns it into a connector that agents call like an API, then repairs itself when the vendor changes a screen.
